In a 27-year-old male with no history of diabetes or hepatitis who develops a rapidly worsening painful rash with skin that cannot be lifted and dysuria after starting a topical cream, what is the appropriate emergency management?

Emergency Management: Immediate Discontinuation of Topical Cream and Transfer to Burn Center/ICU

This patient requires immediate cessation of the topical cream, urgent transfer to a burn center or ICU with experience managing Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), and initiation of supportive care without delay. The clinical presentation—rapidly progressive painful rash with inability to lift skin (suggesting epidermal detachment), dysuria indicating mucosal involvement, and acute worsening after topical medication—is highly concerning for SJS/TEN or severe cutaneous adverse reaction requiring emergency intervention 1.

Immediate Actions at Initial Presentation

1. Discontinue All Suspected Medications

• Stop the topical cream immediately 1
• Document all medications (prescription, over-the-counter, topical) used in the past 2 months 1
• The latency period for drug-induced SJS/TEN is typically 5-28 days, but can be shorter with re-exposure 1

2. Perform Urgent Clinical Assessment

Examine and document:

• Extent of epidermal detachment (not just erythema) using body surface area (BSA) mapping—this has prognostic value 1
• Check for Nikolsky sign (lateral pressure causes skin sloughing)
• Examine all mucosal sites (oral, ocular, genital, urethral) for erosions and blistering 1
• The dysuria and pain with urination strongly suggest urogenital mucosal involvement 1

3. Calculate SCORTEN Within 24 Hours

SCORTEN uses seven parameters to predict mortality and should be calculated on admission 1:

• Age >40 years
• Heart rate >120 bpm
• Malignancy
• BSA detachment >10%
• Serum urea >10 mmol/L
• Serum glucose >14 mmol/L
• Serum bicarbonate <20 mmol/L

4. Initiate Supportive Care Immediately

• Insert urinary catheter given significant dysuria/retention and need for accurate fluid monitoring 1
• Establish IV access through non-lesional skin if possible 1
• Begin appropriate IV fluid resuscitation if clinically indicated 1
• Assess ability to maintain oral hydration/nutrition; insert nasogastric tube if needed 1

Transfer Decision Algorithm

If BSA epidermal detachment >10%: Transfer immediately to burn center or ICU with SJS/TEN experience 1

The evidence strongly demonstrates that:

• Rapid admission to specialized centers improves survival 1
• Delayed transfer is associated with increased mortality 1
• Burn centers have defined protocols for managing extensive skin loss and skin failure 1

Even if BSA appears <10%, the rapid progression described (worsening within hours of cream application) and mucosal involvement (dysuria, inability to urinate) warrant urgent specialist evaluation.

Required Investigations Before/During Transfer

1. Laboratory studies: CBC, CRP, ESR, electrolytes, renal function, liver function, coagulation studies, mycoplasma serology 1
2. Chest X-ray 1
3. Skin biopsy from lesional skin adjacent to blister for histopathology 1
4. Second biopsy from periblister skin sent unfixed for direct immunofluorescence to exclude immunobullous disorders 1
5. Bacterial swabs from lesional skin 1
6. Photographs documenting extent and type of lesions 1

Critical Pitfalls to Avoid

Do Not Continue Topical Treatment

While this case could represent severe contact dermatitis mimicking TEN (as described in one case report with flurbiprofen plaster 2), the clinical approach must assume SJS/TEN until proven otherwise given the life-threatening nature and need for immediate specialized care.

Do Not Delay Transfer for Complete Workup

The investigations can be coordinated with the receiving center. Transfer should not be delayed for biopsy results or complete laboratory evaluation if clinical suspicion is high 1.

Recognize That Topical Agents Can Cause Severe Reactions

Although rare, topical NSAIDs and other topical medications can cause TEN-like dermatoses 2. The fact that this followed topical cream application does not exclude severe cutaneous adverse reaction requiring emergency management.

Specialized Unit Requirements

Once transferred, the patient requires 1:

• Barrier nursing in controlled humidity environment
• Pressure-relieving mattress
• Ambient temperature 25-28°C
• Multidisciplinary team including dermatology/plastic surgery, intensive care, ophthalmology, urology (given genital involvement), and specialized nursing
• Antishear handling techniques to minimize further epidermal detachment 1

Why This Approach Takes Priority

The combination of rapidly progressive skin symptoms, inability to lift skin (suggesting detachment), and painful mucosal involvement (dysuria) creates a medical emergency. The mortality rate for SJS/TEN ranges up to 30% 3, and outcomes are directly linked to speed of recognition, drug withdrawal, and transfer to specialized care 1. Even if this ultimately proves to be severe contact dermatitis rather than true TEN, the initial management approach—immediate drug cessation, supportive care, and specialist evaluation—remains appropriate and potentially life-saving.
